Cummins Pre SCR NOX Sensor
(ENV-NOX-1622)

The Cummins Pre SCR NOx Sensor (ENV-NOX-1622) is a high-precision nitrogen oxide sensor designed for accurate emissions monitoring in Cummins diesel engine aftertreatment systems. Installed before the SCR catalyst, it measures NOx levels in real time and sends data to the ECM to optimize DEF dosing, improve combustion efficiency, and ensure compliance with emission standards. This helps reduce harmful exhaust gases while maintaining strong engine performance and fuel economy. Built with durable, heat-resistant materials, it delivers reliable operation under extreme temperature and heavy-duty conditions. Fully compatible with Cummins systems, it ensures stable readings, long service life, and efficient aftertreatment performance.
